Abstract

This paper deals with a secure satellite-terrestrial multicast framework over shadowed Rician fading channel, where a satellite communicates with legitimate receivers in the appearance of several eavesdroppers. Our main aim focuses on the protection of this multicast messages from wiretapping. The secrecy performance is analyzed by deriving expressions for two secrecy measures such as the ergodic secrecy multicast capacity and secure outage probability for multicasting in closed-form. The derived mathematical expressions provides an useful insight into how the severity of shadowing affects the secrecy performance of the proposed model. Impact of fading, multicast users and number of eavesdropper on the secure outage behavior is also quantified which provides a trade-off between security and the system parameters. At last a close agreement between the analytical and Monte-Carlo simulation results is presented to validate the derived mathematical expressions.

Enhancement of Secrecy Multicast Capacity over k - µ Shadowed Fading Channel

A. S. M. Badrudduza, S. M. S. Shahriyer, Milton Kumar Kundu +1 more

This paper illustrates a secure multicast scenario over k- μ shadowed fading channel in the appearance of multiple eavesdroppers. In order to achieve perfect secrecy, it must be ensured that no eavesdropper can decipher any transmitted information from the multicast channels. The secrecy analysis incorporates deriving mathematical expressions for two secrecy matrices such as the ergodic secrecy multicast capacity and the secure outage probability for multicasting. It is observed that proposed k - μ shadowed model unifies secrecy analysis of some well-known classical fading models and the derived expressions can help to quantify the significant impact of shadowing as-well-as other system parameters on secrecy performance. Finally, a close match between the analytical and Monte-Carlo simulation results is shown which validates the correctness of the derived expressions.

Performance Analysis of Multicasting Over Rician-K Fading Channels: A Secrecy Tradeoff

A. S. M. Badrudduza, M. Z. I. Sarkar, Milton Kumar Kundu +1 more

A secure multicasting framework is considered in this paper to investigate the secrecy performance of a single-input multiple-output (SIMO) system in which a single antenna source transmits private message to multiple receivers in the presence of multiple eavesdroppers. All the receivers and eavesdroppers are equipped with multiple antennas. The perfect secrecy is obtained when evasedroppers can not be able to decode any transmitted information. Considering independent and identically distributed (i.i.d) Rician-K fading channels, the mathematical expressions for the probability of non-zero secrecy multicast capacity, the ergodic secrecy multicast capacity and the secure outage probability for multicasting are derived in closed-forms. Numerical results are provided to show the impact of the diversity provided by the multiple antennas at the receivers. In addition, the impact of Rician factor, K on the secrecy capacity and outage behaviour of the proposed multicasting scenario is also demonstrated. The performance analysis includes the Rayleigh fading scenario as a special case of Rician-K fading channel and focuses the performance comparison between Rician-K and Rayleigh fading channels.

Enhancing Security in Wireless Multicasting over k - µ Fading Channel

A. S. M. Badrudduza, Milton Kumar Kundu

In this paper, a secure wireless multicast network over k - μ fading channel is considered, where a source transmits secret information to a group of receivers. A group of eavesdroppers are also present in the network which are responsible for wiretapping the transmitted information. A perfect secrecy can be obtained if the eavesdroppers are not able to decode any information from the source. In order to investigate the secrecy capacity of the multicast network, at first a novel expression for Ergodic secrecy multicast capacity is derived in closed-form. The outage performance of the proposed network is analyzed obtaining the closed-form expressions of secure outage probability for multicasting. The effects of fading is determined and a beneficent insight is provided into investigating the secrecy performance of some other common fading scenarios such as Rician, Rayleigh, Nakagami-m, Gaussian etc. using the derived novel expressions of this paper. Monte-Carlo simulations are performed to validate the derived analytical expressions.

Opportunistic Relaying in Multicasting over Generalized Shadowed Fading Channels: A PHY Security Analysis.

S. M. S. Shahriyer, A. S. M. Badrudduza, Sarjana Shabab +1 more

The secrecy of wireless multicast networks is greatly hampered due to the simultaneous presence of fading and shadowing, which can be enhanced using random attributes of the propagation medium. This work focuses on utilizing those attributes to enhance the physical layer security (PHY security) performance of a dual-hop wireless multicast network over kappa-mu shadowed fading channel under the wiretapping attempts of multiple eavesdroppers. In order to raise the secrecy level, we employ multiple relays with the best relay selection strategy. Performance analysis has been carried out based on the mathematical modeling in terms of closed-form expressions of the probability of non-zero secrecy multicast capacity, secure outage probability for multicasting, and ergodic secrecy multicast capacity. Capitalizing on those expressions, we analyze how the system parameters (i.e. fading, shadowing, the number of antennas, destination receivers, eavesdroppers, and relays) affect the secrecy performance. Our numerical results show that the detrimental impacts due to fading and shadowing can be remarkably mitigated using the well-known opportunistic relaying technique. Moreover, the proposed model unifies secrecy analysis of several classical models, thereby exhibits enormous versatility than the existing works. Finally, all the numerical results are authenticated utilizing Monte-Carlo simulations.

Secrecy Performance Analysis over Inverse Gamma Composite Multicast Fading Channels

Abdulkarim Al Hanif, A. S. M. Badrudduza, Md. Shakhawat Hossen +2 more

Secrecy performance of realistic wireless multicast scenarios are significantly deteriorated by simultaneous occurrence of multipath and shadowing which are modeled using composite fading channels. To resolve this security threat, in this paper a framework is proposed where a source transmits private multicast messages to multiple receivers over η - μ / inverse gamma composite fading channels. A group of eavesdroppers are trying to overhear this secret communication. Perfect secrecy is obtained if eavesdropper can not decode any information from the multicast links. Secrecy analysis is carried out deriving closed-form expressions of two well-known secrecy measures i.e. probability of non-zero secrecy capacity and secure outage probability for multicasting. The impacts of multipath, shadowing and other system parameters on the outage performance of the proposed scenario are quantified using the derived expressions. A generic nature of η - μ / inverse gamma distribution is obtained by showing Rayleigh, Nakagami-m, Nakagami-q, η - μ fading and Gaussian channels as a special case of this distribution. Finally, Monte-Carlo simulations are presented to verify the derived expressions.

Physical Layer Security of Multiuser Satellite Communication Systems With Channel Estimation Error and Multiple Eavesdroppers

Kefeng Guo, Kang An, Yuzhen Huang +1 more

This paper investigates the physical layer security (PLS) for the transmission of confidential information over satellite communication systems under unified framework. The generalized shadowed-Rician (SR) fading is utilized to model the satellite channel, and multiple legitimate users are served to cooperatively receive the broadcast signal with a cluster of unauthorized eavesdroppers. In particular, the channel estimation error (CEE) is considered for both the legitimate user and eavesdropping links. Based on the practical channel modeling, we derive the closed-form expressions for the probability of strictly positive secrecy capacity (PSPSC), secrecy outage probability (SOP), and average secrecy capacity (ASC) of the considered satellite communication system in the presence of imperfect channel estimation (ICE), which can provide efficient methods to evaluate the impacts of various propagation parameters on the secrecy performance. In order to obtain further insights into the key parameters on the secrecy performance at high signal-to-noise ratios (SNRs), the asymptotic expressions of the SOP and ASC are also derived. Monte Carlo simulation results are provided to verify the correctness of our performance analysis.
